Feb. 3, 2011 is a date that will live in infamy -- for some of us, anyway. That day marked the last time IANA will allocate a fresh /8 netblock to one of the Regional Internet Registries (ARIN, RIPE, and so on).
One could legitimately say that the Internet is indeed out of IPv4 addresses right now, but the pain won't really be felt until the RIRs deplete their allocations and ISPs burn through what they've already been allocated. That date will vary depending upon what part of the world you live in. The Asia-Pacific region is slated to run out first, but everyone else is close behind. Getting a good old dotted-quad IPv4 allocation from your ISP is going to be a fun bedtime story you can tell your kids within the next year or two.
